Types of Data Deduplication

Arcserve UDP supports the following two types of data deduplication.

Source-side Data Deduplication

Ensures that only unique data from the agent is sent to a recovery point server for data backup.

Global Deduplication

Ensures that only unique data from multiple agents are backed up to a recovery point server. If similar data blocks are present on multiple nodes, only one copy is backed up to the recovery point server.
